NORTH AMERICAN COLEOPTERA. 89 



Tliis is one of our sniallei^t species. It is known by the single spot 

 on each elytron a little in front of middle. There are six ventral 

 segments. 



Hab. — Florida, Punta (jrorda and Biscayne Bay. 



S. liiebeoki n. sp. — Oval, convex, a slight entering angle at base of thorax, 

 head and thorax yellow, the latter darker in front of scutellum, elytra piceous, a 

 narrow, ajiical, pale border, a small round yellow spot in front of middle nearer 

 the suture than side, a slightly sinuous transverse band one-third from apex 

 touching the side, but not the suture. Head scarcely punctate. Thorax distinctly 

 punctate, not closely nor coarsely, a fine basal marginal line. Elytra moderately, 

 coarsely and closely punctate ; prosternal plate slightly narrowed in front, with 

 feebly indicated, lateral, elevated lines ; nietasternum closely punctate at the 

 sides, the mesocoxal line joining the suture at a right angle near its middle. 

 Abdomen reddish yellow, punctate ; metacoxal line joining the suture and con- 

 tinuous with it. Legs yellow. Length .05 — .06 inch. ; 1.25 — 1.5 mm. PI. I, fig. 6. 



The abdomen has six distinct segments. At first glance this spe- 

 cies resembles eoltrradendx, but in that species the anterior elytral 

 spot is larger, the posterior differently formed, and the metacoxal 

 line is distant from the suture. 



Hab. — Southern New Jersey, collected by Mr. Charles Liebeck, 

 whose name I have pleasure in giving to the species. 



Specimens very recently examined from Elkhart, Ind., have a 

 well-marked, thoracic, piceous .spot. The posterior elytral spot is 

 also oval and not transverse, the markings thus I'e.sembling myrmidon. 



S. inyrnii<loii Muls. — Oval, black, shining, each elytron with two sharply- 

 defined yellow spot.s, placed one-third from base and one-third from apes, nearer 

 the suture than the side, apical border very narrowly and indistinctly pale. Head 

 brown, or paler, sparsely finely punctate. Thorax narrower in front, sides mod- 

 erately arcuate, sparsely finely punctate, a little more closely near the base, a fine 

 basal marginal line. Elytra much more coarsely punctate, not closely but equally. 

 Prostenial plate smooth, triangular; metasternum at sides sparsely punctate, 

 mesocoxal line joining the suture one-third from the front. Abdomen rather 

 sparsely punctate, shining, the metacoxal line joins the first suture and runs coin- 

 cident with it: femora piceous, tibite and tarsi yellow. Ijength .06— .08 inch.; 

 1.5—2 mm. PI. I, fig. 9. 



The abdomen is brownish, paler toward a])ex or yellow, composed 

 of six distinct segments, the first sutui-e less distinct at middle. 

 Hab. — Pennsylvania, Maryland. 



S. qiia<lritH^lliatllK Lee— Oblong, fully one-third longer than wide, pi- 

 ceous, head and side of thorax yellow, each elytron with two yellow spots, the 

 anterior lai-ger, oblique and oval, the posterior reniform and transverse. Head 

 scarcely punctate. Thorax slightly narrower in front, sides moderately arcuate, 

 surface moderately closely punctate, especially at the sides. Elytra n ore sparsely
